London Jobs - January 2023

Optimal | Senior Full Stack and MLOps | Full-Time | London | Hybrid | https://www.optimal.ag/

We develop software to control the environment within large (>2Ha) greenhouses to make them more profitable and scalable. This is a $10B industry in Europe (particularly the Netherlands), though few outside agriculture seem to know about it! A major difference compared to vertical farms is that greenhouses are already profitably selling mass market crops (Tomatoes, Cucumbers, Peppers…). We see an opportunity to further automate greenhouses and enable them to be deployed at scale across the world.

Funding: we have recently closed our Series A. This funding round was raised off the back of trials of our technology in Dutch greenhouses for the past two years.

Team: 11-person team of engineers based in London with plant scientists in the Netherlands. We plan to carefully expand this team over the next two years.

Working arrangements: hybrid model with 3 WFH days.

Roles: We are looking for strong engineers who want to join at a critical point in the company’s journey. Open roles:

Evertas Insurance | US-based REMOTE | Full-time | https://www.evertas.com/ | https://www.evertas.com/careers/

Evertas is the world's first cryptoasset insurance company. We're a Bermuda carrier, Lloyd's of London cover-holder, and have been around for almost 5 years. We write real policies which actually cover significant risk for clients, quantify premiums based on the effectiveness of deployed controls, and do professional services for clients to put better controls in place (or helping other insurance companies with underwriting and claims adjustments).

The best pitch for the company is: Join us to prevent the next SBF/FTX/3AC/Luna/Celsius... meltdown, by providing tools for the industry to police itself, provide meaningful risk transference, ensure best practices are documented and commercially required, and avoid uninformed and unproductive government regulatory retaliation instead of meaningful public/private beneficial governance -- and make a bunch of money for everyone while doing so.

(I'm Chief Security Officer; have been involved in crypto since the 1990s (blinded tokens), and I love insurance as a powerful tool to improve security across the industry. The rest of the team are also cryptocurrency and security OGs, with industry and institutional experience.)

Among other roles, we're looking to hire 1-2 Security Engineers. Primarily this is for underwriting and professional services in the cryptocurrency space, as well as research into risks in the space (and mitigations). A great thing about insurance is it's not "call in the middle of the night over a holiday with a crisis", but solving things prospectively for clients, but still having significant and meaningful impact.

We're open to security experts moving into cryptocurrency, or cryptocurrency experts moving into security, but obviously having interest in both is key (and expertise in both would be amazing). We highly value professionalism, integrity, and a problem-solving nature. Would be very interested in people who currently or recently worked at downsizing, technically excellent security teams in the crypto industry or in security-critical adjacent industries.

Please apply through the form at https://www.evertas.com/careers/ (PLEASE NO RECRUITERS)

Genpax | Engineers (full stack, frontend/backend, product, devops) | London, UK | ONSITE (hybrid/flexible) | https://www.genpax.co/

Genpax is building a game-changing bacterial analysis platform. Using bioinformatics, we can help hospitals take early and effective action against outbreaks of MRSA and other pathogens. This is an opportunity to have a real-world impact on thousands of lives each year.

At Genpax our goal is to radically increase the utility, scalability, and speed with which whole genome sequencing (WGS) data delivers infection control solutions for human and animal healthcare worldwide. This will enable proactive control at early stages of outbreaks, and to respond appropriately to more dangerous or more antibiotic resistant strains. We have developed unique solutions to address the challenges and our goal is to provide access to these solutions in a fully scalable system.

There are really interesting engineering problems to be solved: scaling and optimising our analysis pipeline and the bioinformatics algorithms we use; building out our interactive graph-based user-facing product; developing cryptographic techniques for analysis of anonymised data. At the moment we're using Python, GraphQL, React/TypeScript, Postgres and AWS.

£45-95k + equity, based on experience.

## About Us

Symmetry Investments is a post startup multi-billion alternative asset management company with 250+ people across multiple time zones and locations.

Our core technology team has been remote-first for some time, and the whole company is following suit, accelerated by the pandemic.

We are five years into a period of transformation from what was initially a fairly standard enterprise finance technology approach to something new that recognises the importance of both the humane and the technical for discretionary portfolio management and for the business of running an alternative investment manager. [Amaury Sechet](https://www.youtube.com/watch?v=AhR4PSExnqk) and [Atila Neves](https://dlang.org/blog/2019/10/15/my-vision-of-ds-future/) have been working with us as long-term consultants and we have many other talented people with lower public profiles.

It's not easy to integrate practitioners who may spend most of their day programming, but are oriented towards solving business problems, with developers who are specialists in programming. To achieve this, we wrote a little functional DSL that's now in production. Type inference of returns and parameters using inequality constraints is in a feature branch and there is plenty more to do on the language itself as well as the ecosystem around it. SIL can compile and call C++, D, and C# at runtime and interoperate with Python and R. What might be a project in itself elsewhere can be just a set of functions in Symmetry Integration Language.

The language is written in D and we have a close involvement with the D Foundation and community, hosting DConf in London. So we are looking for outstanding native code developers who would like to write D as well as people to work with practitioners writing Symmetry Integration Language. Also looking for people to write documentation and work on the build.

It's quite a creative place where we encourage a degree of courage amidst practical constraints, and we are open to doing things a different way if it's commercially sound and in the interests of our investors.

We look for virtues and capabilities over only experience and credentials although those things aren't a disadvantage. Do not let a lack of credentials or qualifications prevent you from applying. We've recently hired experts with C++, Common Lisp, D, Haxe, Haskell, Julia and Perl backgrounds, and are happy to bring them up to speed with the tools we use.

Compensation is currently not quite at Netflix standards but is generous to very generous over time by broad technology industry standards. We recognise and reward technical accomplishment and have a very flat structure - don't be surprised if our founder and Chief Investment Officer starts asking you questions about your work.
